SI-IEET-STAPLING MACHINE.

Specification of Letters Patent.

Patented An 20, 1918.

Application filed October 13, 1917. Serial No. 198,415.

To all whom it may concern:

Be it known that I, DAMEL A. I-IorriNo, a citizen of the United States, residing at Sturgis, county of St. Joseph, State of Michigan, have invented certain new and useful Improvements in Sheet-Stapling Machines, of which the following is a specification.

This invention relates to improvements in sheet stapling machines.

My improved book stapling machine is especially designed by me for use in the manufacture of sales books and I have illustrated the same as embodied in a structure adapted for that purpose, although my improvements may be readily embodied and adapted for use in stapling other types of books or sheets.

The main objects of this invention are:

First, to provide in a stapling machine an improved means for feeding books to and supporting them to properly receive the staples.

Second, to provide an improved feed mechanism for staplingmachines in which the pad or bundle of sheets may be easily placed in the machine.

Third, to provide an improved feed mech anism for stapling machines in which the sheets are effectively jogged up and sup ported to receive the staples.

Fourth, to provide in a stapling machine a feed means of large capacity.

Fifth. to provide an improved feed means for a stapling machine adapted to deliver the stapled books in a convenient manner for handling or packaging.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a detail plan view of a structure embodying the features of my invention, the stapling head being indicated by dotted lines.

Fig. II is a side elevation with the stapline mechanism shown more or less conventionally.

Fig. III is a vertical longitudinal section on a line corresponding to line of Fig. I.

Fig. XI is a perspective view of one of the sheet clamps removed from the conveyer.

Fig. XIIis a perspective view of one of the conveyer flights.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines. Iteferring to the drawing, the numeral 1 indicates the stapler mechanism generally. As the details of this mechanism, other than the control thereof, form no part of my present invention they are not further described herein.

The stapler mechanism is supported on a pedestal 2. My improvements are illustrated in operative relation to the stapler proper.

I provide a frame consisting of the uprights 3 and horizontal pieces l. A pair of ways 5 is mounted on the frame to face inwardly and support the top reach at the conreyer chain (3. These ways pr; ctice. formed of a pair of spaced saeet inetal members 7 and T,uec l i s. and X. of considerable width, the aiiirantage of which will appear later. The rear ends of the ways are directed downwardly it 8 at the ear end of the frame.

A feed table 19 is disposed at the front; end of the conve r so that the opera tor nia stand -n front of tl l its ible with the uni or bundles of sheets stacked thereon and lay the same upon the conreyer between the digh and clamping yaw. A

A guide 20 is lisposed at the rear of the conveyer. This guide is prefeiahl adjust-- the clainpinp" ably supported hit means 4 screws 21 which engage in horizontal arms of the guide. an angled strip of metal.

The plunger is returned by the coiled spring 75.

As stated, the ratchet wheels 49 and 50, have a different number of teeth, and the gears 67 and 6S and the cams vary accordingly.

The lunger 71 acts upon the tappet 76, which is adj ustably supported so that it may be shifted to and from operative position. 1V hen in operative position the stapler is continuously actuated until the roller 73 drops into the dwell 77 of the cam, which allows the lever 65 to rise and stop the stapler. This takes place during the feed step of the conveyer, which carries the con veycr flights and clamps past the stapling mechanism, the parts being otherwise timed so that the stapler acts during the period of rest between each stroke of the conveyer.

To permit the stopping of the stapler as occasion may require, the tappet 76 is mounted on the slide 78 carried by the depending arm on the bracket 79. A spring 80 holds this slide normally in operative position. The tappet is slotted to receive the end of the slide, the coiled spring 81 holding the tappet normally against the end of the plunger. This slide is connected to the lever 82 pivoted at 83 and connected by the link Si to an arm 85 on the rock shaft 86. This rock shaft is provided with a foot piece 87.

The coiled spring 88 is connected to the link to retract or return the same, so that as soon as the foot piece is released the spring retracts the link 8i, thus throwing the tappet into operative position.

The rock shaft is positioned so that the foot piece is readily accessible to the operator placing the pads in the conveyer pockets.

The stitched or stapled pads are delivered into the receiving trough 89 positioned at the rear of the conveyer so that the pads are carried into the trough by the conveyer.

A support 90 is arranged in the trough so that the pads are delivered on edge in front thereof. A releasing trip 91.is positioned to engage the tails 17 of the jaws as the stitched pads are carried into the trough,-

Fig. 111, so that they are released and deposited in the trough successively. When the jaws pass from the trip 91 they close again and remain closed until they pass over the strip 18 which swings them to open position, so that the pads or bundles of sheets may be slipped into the conveyer pockets.

The rear end of the plate 18 is disposed so that the jaws are released gradually and permitted to grip the pads immediately after the sheets are jogged up by the jogger 23 and are held by the jaws during the stapling process and until the stitched or stapled pads are delivered into the receiving trough.

My improved mechanism is especially well adapted for the stitching of pads used in sales books, although advantageous for use in the manufacture of writing tablets and other articles of manufacture in which sheets are stapled together.

I have not attempted to illustrate or describe various modifications and embodiments of my improvements which I contemplate, as I believe the disclosure made will enable the adaptation and use thereof as circumstances and conditions may render most desirable.
